My plot idea for The Force Unleashed II (my last idea came out uncannily similar)

After Starkiller's death, Darth Vader and the Emperor put his body in storage on the Death Star. When the Rebels come around for the Battle of Yavin, Starkiller strangely gains his senses back, however, he has no memory of his past life. This puts you into the first mission of the game, trying to escape the Death Star before it explodes.

Having no idea who he is, Starkiller realizes his great potential in the force and lightsaber combat whilst escaping the Death Star. Now a fugitive from the Empire, and having no sense of identity, Starkiller makes a living fighting in underground rancor fighting pits, whilst being tormented by the voices of Darth Vader and Yoda, having no idea who they are.
